Plsql 第6行错误：PL/SQL:SQL语句被忽略

第6行出现错误：

PL/SQL:SQL语句被忽略

带有“

”select count（*）into ecount“

的行给出了错误

有人能帮我吗

我的代码：

   create or replace function empcount(department in table_employee.dept_name%type)
   return integer
   as 
   ecount integer;
   begin
   select count(*) into ecount
   from table_employee 
   where table_employee.dept_name=deparment and salary>500000;
   return ecount;
   end;

：

create or replace function empcount(department in table_employee.dept_name%type)
                                    ^^^^^^^^^^
                                    vvvvvvvvv
 where table_employee.dept_name    =deparment and salary>500000;

除此之外，您还可以：

SQL> create or replace function empcount
  2    (department in table_employee.dept_name%type)
  3    return integer
  4  as
  5    ecount integer;
  6  begin
  7    select count(*) into ecount
  8      from table_employee
  9      where table_employee.dept_name = department      --> fixed
 10        and salary > 50000;
 11    return ecount;
 12  end;
 13  /

Function created.

SQL> select empcount(20) from dual;

EMPCOUNT(20)
------------
           2
